BP2 OPERATOR’S MANUAL
CHANGING THE FUSE_______________________________________________________________
If the BP2 fails to operate when the “ON” button is depressed, confirm that the battery is connected. If its
connected, confirm that is fully charged. If the battery is fully charged, disconnect it and remove it from the BP2.
Locate the two screws in the cover panel above the battery and remove them. Locate the yellow fuse holder, open it
and inspect the fuse.
If it is blown, replace it with another 20A fuse and reassemble the fuse holder. Reinstall the cover panel and reinstall
the battery, reconnecting the red and black connectors to the matching ones in the BP2.
If the fuse is not blown, or it blows again when the “ON” switch is depressed, please contact ESS Customer Service.

BATTERY CHARGING OPERATION___________________________________________________
Disconnect the red and black connectors from the battery. Remove the
battery from the BP2 and follow the instructions below to charge:
1. Only use 29.2V, LiFE PO4compatible chargers to charge the battery.
The charging current should be 2A to 4A. If you need a charger,
please contact us.
2. Fully charge the battery before first use. This depends on the output
of the charger but is typically between 3-5 hours.
3. Note that the LED light on the battery does NOT indicate the state of
charge. A red LED light means the battery is under constant current
(CC) charging and green LED means constant voltage (CV) charging.
Always charge for at least 5 hours to ensure full capacity.

LiFe PO4 does note suffer “memory effect” so please keep the
battery fully charged for daily use. Cell balancing only occurs when
the battery is fully charged (top-end balancing).
